RESUMO
Objective To analyze the main active components and potential molecular mechanism of Sophora flavescens against breast cancer based on network pharmacology and molecular docking. Methods The chemical constituents were collected and screened by TCMSP, ETCM database and literature review. The targets of active ingredients were predicted by Swiss Target Prediction database. Breast cancer-related targets were collected by GeneCards, TTD, Drugbank and OMIM. The anti-breast cancer targets of Sophora flavescens were screened by Venny 2.1.0 software. Cytoscape software was used to construct the network diagram of Sophora flavescens-key active ingredients-targets. STRING database was used to analyze the common targets, and PPI network diagram was constructed. GO function enrichment analysis and KEGG pathway enrichment analysis of key target proteins were performed by DAVID database and Hiplot online platform. Schrodinger software was used to calculate the molecular docking between the active ingredients and targets. Molecular biological methods were used to verify the key targets. Results A total of 36 active components with clear structures were screened from Sophora flavescens. 70 anti-breast cancer targets of Sophora flavescens were screened out. 12 core targets including EGFR, AKT1, ESR1, SRC, CYP19A1, AR and ABCB1 participate in endocrine resistance, EGFR tyrosine kinase inhibitors and estrogen signaling pathways in breast cancer. Moreover, the docking score between the core component and the key target AR is the highest. In vitro experiments showed that the extract of Sophora flavescens can inhibit the proliferation of breast cancer cells, induce cell apoptosis and up-regulate AR protein expression. Conclusion It was revealed that Sophora flavescens plays an anti-breast cancer role by regulating complex biological processes through multiple components acting on multiple targets and signaling pathways. The upregulation of AR protein by Sophora flavescens may become a new therapeutic strategy for the treatment of breast cancer.

RESUMO
Objective:To determine classification and clinical features of morphea.Methods:A retrospective analysis was conducted on epidemiological information about clinical manifestations of and laboratory data from 180 patients with morphea, who visited Zhongshan Hospital, Fudan University from January 2010 to July 2021. Two-independent-sample t test was used to compare the age at onset between genders, and chi-square test to analyze differences in clinical characteristics between different genders and subtypes. Results:Among the 180 patients, 123 were females and 57 were males, with a male-to-female ratio of 1∶2.16. The age at onset of morphea was 28.69 ± 17.97 years for female patients, and 29.90 ± 20.67 years for male patients. Among them, linear morphea was the most common type in this study (68 cases, 37.78%), followed by plaque morphea (63 cases, 35.00%), mixed morphea (28 cases, 15.56%) and deep morphea (21 cases, 11.67%). The disease occurred in all age groups, but the age at onset significantly varied among different clinical subtypes ( F = 5.95, P < 0.001). No significant difference was observed in the age at onset or proportion of clinical subtypes between genders ( F = 0.15, P = 0.696; χ2 =2.88, P = 0.410). Atrophoderma of Pasini and Pierini (APP) was very common (62 cases, 34.44%) in the 180 patients, which mainly manifested as plaques or linear lesions, and 26 out of 45 patients with plaque APP and 11 out of 17 with linear APP were both accompanied by other subtypes of morphea. Among the 75 patients tested for autoantibody profiles, 34 (45.33%) presented with positive results. More diverse types of autoantibodies were found in female patients compared with male patients, and antinuclear antibodies, anti-SSA and anti-SSB antibodies were the most common types. There were various types of comorbidities in female patients, but lichen sclerosus et atrophicus and vitiligo were the most common comorbidities in both genders. Conclusion:High incidence and frequent co-occurrence with other subtypes of APP may be the characteristics of Chinese patients with morphea, and it is recommended to classify morphea into plaque, linear, deep and mixed subtypes.
RESUMO
Paclitaxel is the first-line chemotherapy drug for a variety of cancers. However， the paclitaxel resistance greatly reduced the efficacy in the later treatment stage， which seriously increased the mortality and recurrence rate of cancer and limited the clinical application of paclitaxel. At present， Chinese medicine compound prescription， proprietary Chinese medicine， and Chinese medicine injection are widely used as the adjuvant chemotherapy drugs for the treatment of cancer in clinic. Chinese medicine has shown unique advantages in improving the efficacy of chemotherapy drugs and the prognosis of chemotherapy， and reducing the toxic and side effects. However， the specific mechanism and effective monomer composition of Chinese medicine for reversing the resistance of chemotherapy drugs are unclear， and the application of Chinese medicine in different types of cancer is also limited， which are worthy of further exploration. This review summarized the composition of Chinese medicine monomer with synergistic antitumor effect combined with paclitaxel in recent years. The specific mechanism and pharmacological activities of Chinese medicine monomer reversing paclitaxel resistance were classified. This review found that through acting on the membrane transport protein， Chinese medicine monomer promoted the accumulation of paclitaxel in tumor cells， inhibited the expressions of protein and metabolic enzyme related to multidrug resistance and the metabolism of paclitaxel， and regulated the levels of apoptosis genes and factors and apoptosis-related pathways to promote the inhibitory effect of paclitaxel on cell proliferation. Chinese medicine monomer also significantly improved paclitaxel chemotherapy sensitivity by regulating the expression levels of micro ribonucleic acid （microRNA） and long non-coding ribonucleic acid RNA （lncRNA）， inhibiting the characteristics of tumor stem cells and tumor metabolic reprogramming， improving tumor microenvironment， and triggering tumor cell death autophagy and oxidative stress response. This review provides a theoretical basis for clarifying the specific anti-tumor mechanism of Chinese medicine monomer combined with paclitaxel， which is of great significance for the development of new Chinese medicine and the clinical research of the drugs combined with paclitaxel， and has certain value for the application of Chinese medicine combined with other chemotherapy drugs.
RESUMO
Objective:To explore the relationship between childhood trauma and aggressive behavior in patients with major depressive disorder(MDD), and the mediating role of self-esteem in childhood trauma and aggression.Methods:A total of 241 MDD patients with childhood trauma were investigated by Chinese version of the Buss & Perry aggression questionnaire(AQ-CV) and self-esteem scale (SES). Data were analyzed by SPSS 23.0 and AMOS 24.0.Pearson correlation analysis was used to assess the correlation of childhood trauma, aggressive behavior and self-esteem.The Bootstrap method was applied to test the mediating effect of self-esteem between childhood trauma and aggressive behavior.Results:The total score of attack questionnaire, self-esteem and childhood trauma were (48.81±18.81), (24.91±5.29)and(53.87±10.43), respectively. Self-esteem of MDD patients was negatively correlated with aggressive behavior and childhood trauma ( r=-0.45, -0.24, P<0.01). Childhood trauma was positively correlated with aggressive behavior ( r=0.42, P<0.01). The direct effect of childhood trauma on aggressive behavior was 0.438(95% CI: 0.305, 0.579). Self-esteem played a partly mediating effect between childhood trauma and aggressive behavior, and the mediating effect value was 0.161 (95% CI: 0.080, 0.256), accounted for 26.9% of the total effect. Conclusion:Self-esteem plays a partly mediating role between childhood trauma and aggressive behavior.Childhood trauma can directly and through the part of mediating role of self-esteem affect aggressive behavior.
